The hard drive on my old TiVo Series 3 HD has failed completely. It was running for years with a 1TB hard drive which no longer works at all. I have purchased a new 1TB hard drive but don't have the image for this drive to be able to use it I'm my old, formally reliable, TiVo (btw, it has lifetime service). I also have a TiVo Roamio which will format a blank drive with no additional software needed but this format won't work in the old series 3. I cannot get anything from the old drive. Can anyone help me out with this? I have both a Windows 7 laptop as well an iMac to use for setting up the TiVo drive. Thanks to all for your help.
